Abstract: A mesoporous alumina-ceria composite catalyst supported with copper oxide by using copper oxide as an active material, and utilizing ceria for improving activity of an oxidation reaction and alumina for increasing structural stability of ceria is provided, and a method for selectively oxidizing carbon monoxide using the alumina-ceria composite catalyst supported with copper oxide is provided. A preparation method of a copper oxide-supported alumina-ceria composite catalyst comprises the steps of: (a) mixing an alumina precursor, a ceria precursor, and a copper oxide precursor with a mixed solvent of a surfactant and alcohol to form a micelle; (b) adding water into the solution obtained in the step(a) and agitating a mixture of water and the solution to subject the mixture to a hydrolysis reaction and a condensation reaction; and (c) drying a resulting material of the step(b) and heat-treating the dried resulting material at 350 to 550 deg.C.
